Solar energy is an alternative, renewable and sustainable energy that uses sunlight as an energy source and can be used and exploited through various technologies such as solar heating, photovoltaics, and heliothermal energy. Active solar technologies include photovoltaic systems, centralized solar power, and solar water heating for energy recovery.
In 2011, the International Energy Agency stated that “the development of affordable, affordable and clean solar energy technologies has enormous long-term benefits. It will increase countries’ energy security based mainly on indigenous peoples, scarce, and independent import resources. Benefits of this globalization. Wisely and extensively.
What is solar energy? Get everything you need
Solar energy is sustainable alternative energy from sunlight that can produce electricity (solar energy) and thermal water (solar power). The concept of Energia solar is often associated with photovoltaics, which is the production of electrical energy using sunlight as an energy source. So it can be said that solar and photovoltaics are the same thing.
When solar panels absorb sunlight, electricity is converted for use in homes, businesses, and industries.
Nuclear fusion reactions in the sun generate this type of renewable energy. The radiation travels to the ground through electromagnetic radiation and can be used later. Solar energy can be used in the form of thermal or electrical energy for later consumption if needed. For thermal energy, we get heat to heat liquids.The most important feature is to capture and convert solar radiation into usable energy for the Panels Solars. Solar panels can be of different types depending on the mechanism chosen to use solar energy:
Three solar collectors (solar energy)
Using a photovoltaic panel (photovoltaic)
No external element (passive solar energy)
How to use solar energy
There are countless ways to harness solar energy, which makes the development of our country usable. Therefore, its energy matrix can be studied in a sustainable, renewable, and economical way:
Shared systems such as electricity generation for schools, health centers, and multipurpose buildings.
Types of solar energy
Solar energy can be used to generate electricity with two systems: heliothermal and photovoltaic.
Photovoltaic solar energy
Photovoltaic solar energy is nothing more than the conversion of solar radiation into electrical energy. This transformation takes place in the so-called For solar cells consisting of a semiconductor material, usually silicon. When it acts on cells, sunlight causes electrons to move in a conductive material, carrying them through the material until they are trapped in an electric field (formed by a potential difference between semiconductors). In this way, electricity is generated.
The photovoltaic system consists of:
solar panel mounting system
and other standard electrical materials
Heliothermal solar energy
Solar energy is converted into heat, mainly by heating water in homes, hotels, and clubs. To make this possible, solar panels (mirrors, collectors, heliostats) are used that reflect sunlight, focusing on one point with a receiver.
The receiver consists of a liquid that is heated by sunlight reflected on the panels. This fluid is responsible for storing heat, heating water in plants, and producing steam. This steam drives the turbines in the plants, causing the generators to start and generate electrical energy.
Producing solar energy when there is no sun.
The panels work on cloudy and rainy days, as they depend on the frequency of purple rays and not on heat, so there is solar energy when there is no sun. Production changes on gray days, but it is still there. At night there is no catch, but there are batteries to ensure energy accumulation.
If the day is rainy, cloudy, or dark, it does not mean that you will not be able to use the sun’s energy when there is no sun. Therefore, it is essential to point out that.
Energia Solar. It is captured by the frequency of ultraviolet rays and not from the sun’s heat, operating in a reduced way but still functioning.
Therefore, a professional who considers the average heatstroke in the region where the installation will occur and the energy capacity is needed. This way, it will be possible to find out the sun level and avoid a low yield on cloudy or rainy days since the calculation will be done by the sun’s location, the sun’s index during the year, and the length of the day.
In this sense, with the help of high-quality photovoltaic solar panels, the generators’ efficiency can be guaranteed even in the absence of sunlight, as the generated load is sufficient. The same does not happen at night; however, since the photovoltaic system cannot generate energy when there is a no different light, it requires the distributor to use electricity.
